PERM UTATlON-LOCK.

SPECIFICATION forming part of Letters Patent No. 512,506, dated January 9, 1894.

Application filed March 2l), 1893. Serial No. 468.182. (No model.)

To @ZZ whom it may concern:

Be it known that JosIAH J. DEAL, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Commutation-Locks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specication.

My invention relates to improvements in commutation locks, and consists ot certain features of construction and combination of parts as will be hereinafter described and pointed out in the claims.

Figure 1, of the accompanying drawings is a view in perspective illustrating my invention as applied to a door lock. Fig. 2, is a longitudinal section ofthe same. Fig. 3, is a View of the face of one of the disks. Fig. 4, is a perspective of one of the locking disks. Fig. 5, is a perspective of thelock as applied to a shackle for padlock. Fig. 6, is a longitudinalsection of same, and Fig. 7, is a perspective showing the form of the locking and spacing disks. l

Referring to Fig. 2, A represents the knob bar or spindle on one end of which is-provided a series ot grooves numbered 1, 2, 3, 4, 5, 6, and a series of alternating collars, c, b, c, cZ, e, f; at the end portion of the spindle is a pin Z1, projecting a distance from the sides as shown. B, represents the knob, and C a retaining plate. Between the knob and retain-` ing plate is placed alternately a series of locking disks, y', Zo, Z, m, fn, o, p, and spacing disks q, and at the end portion next the knob a locking disk r in form substantially as that shown in Fig. 3, having side apertures Vu to receive the bolts t, and a central aperture o, having sidevkerfs s to secure the end of the spindle A and the projecting pins Zt. The locking disks R are of the form shown in Figs. 4 and 7, having a side aperture u, a

central aperture o, that overreaches and cuts into a side aperture w which is of less diameter, thus forming across the disk an elongated aperture of two intersecting circles or apertures of different diameters. At

the side opposite the aperture u is an elongated aperture oc, and atthe same side an outwardly projected finger portion y. The bolt t is passed through the aperture u, which serves as a pivot about which the locking disks R may be vibrated a distance to lock or release the parts as hereinafter described.

The parts are preferably assembled as shown in Figs. 1 and 2, that is, finger portions y, projecting from opposite sides to all low of more room for manipulation; the bolts Z are passed through apertures u in the retaining plate and similar apertures in the spacing plates q, and the locking plate r, and turned into threaded apertures in the knob by which the parts are held in position.

To provide for a slight contraction or expansion of the bolts and disks, a groove is provided in the under side of the retaining disk C, and a spring z as shown in Fig. 7, is placed therein the energy of which is exerted against the disk next thereto.

The knob as shown in Fig. 2, is unlocked or loose and free to turn on the spindle A, without moving the latch bolt D of the door lock; the locking operating disks are placed to move transverse the spindle in opposite directions; referring to Fig. 2, it will be seen that the small part w, of the aperture embraces the small part of the spindle in the groove Z, between the shoulder on the spindle and collar o. Disk 7c, occupies a similar position between the collars b, c, and disk m, a similar position between the collars f, and the locking plate fr. Disk n, on the opposite side occupies a similar position, the small part w of the aperture embracing the small part of the spindle in the groove e, between the collar a, b, to prevent a longitudinal movement of the lock and knob on the spindle. Itwill also be noticed that the large part e of the lock set on combination or disks j, Za, fn of the '9 disks pivoted on the bolts t. Disks j and Ze, are

moved to the right, and n to the left which movement will bring the large part fu, of the aperture inthe disk in register with o, Z, p. The knob may now be drawn out a distance IOO on the spindle, the pins h passing into the kerf s', thereby locking the knob to the spin dle for the purpose of rotating it to move the lock bolt D. The disks may now be thrown in confusion to remain so until it is desired to disengage the knob to lock the door. In other Words the knob is unlocked from the spindle to lock the door lock.

To change the combination, the opposite knob is removed, the spindle with the cornmutation lock removed from the door lock, and the bolts t, taken out, after which the locking disks R may be turned over to occupy the same position, but to swing in the opposite direction, or they may be turned end for end and pivoted on the opposite bolt or may occupy another place in series; thus it will be seen that an almost indefinite number of combinations may be had. It will be understood that the letter R designates the movable locking disks. The letters .7', k, Z, m, dac., are used to designate their position in the combination or commutation.

The spindle with the commutation lock attached may be applied to any form of knob, latchlock, orthe commutation parts may be applied to a padlock shackle as represented by the parts shown in Figs. .6 and 7.

Referring to Fig. 6, E represents aT shackle having head portion a ,transverse the neck a2, and a shank a3, in which are provided grooves l, 2, 3, 4, 5, 6, and collars a, b, c, d, e, f, as shown on the lock spindle A, Fig. 2. The locking disks j, k, Z, n, o, p, and the spacing disks q, and retaining disk C, are fac-similes of the parts shown in Fig. 2. A plate or disk F, is provided having threaded apertures to receive the ends of the bolts t, in place of the knob B. The smaller partw, of the aperture in the movable or locking disks j, 7c, n, o embraces the smaller part of the shank and co1- lars a, b, c, d. To prevent the removal ofthe bolts t, when the lock is in service, an apertured plate or disk Gis placed over the heads of thebolts and securedto theplateCby a small screw H, turned into a threaded aperture in the retaining disk G, the head portion of the Screw to be under or partly under the shoulder of the shank.

This lock is set on the combinationj, 7cm, o. j, k, are turned to the right, and n, o, to the left, to arrange the large part c of the aperture in the disks in line with the collars, so that the shank ot' the shackle may be drawn out of the lock.

The 'combinationsgiven are of the simplest to illustrate the workin g f the lock, but other and more complicated combinations would be adopted in practice.

Having thus fully described the object and nature of my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with a door lock spindle having a series of prjecting portions of a series of spacing disks, a series ot' locking disks adapted for transverse vibration to carry said disks between said projections to lock said parts against longitudinal movement on the spindle for the purpose set forth.

2. The combination with a door lock spindle having a series of depressions andprojec- `tions of a series of locking disks adapted to vibrate transverse .said spindle to release the parts and allow the knob `to `move longitudinally on said spindle, a locking disk r and pin h, whereby the knob is locked or engage with the spindle for the purpose set forth.

3. Thecombination with a door lock spindle having a series of grooves and collars, of the spacing disks, the knob B, retainingidisk C, bolts t, and disks R, adapted to vibrate transverse the bolts to engage or disengage the spindle, substantially as described and for the purpose set forth.

4. The combination with a lock shackle having a head portion a', transverse the neck a2, a shank a3, having a series of alternating grooves and collars, of the spacing disks q, the locking disks R, and bolts t, about which the disks R may be vibrated transverse the shackle, substantially asi described and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 25th day of March, A. D. l893.
